Sisyphus rolls his stone in Odyssey XI (Book 11, the nekuia), among the punished of Hades. The mythic dossier, assembled in later sources including Apollodorus's Library (1.9.3, 2.5.1), gives the crimes: he chained Death (Thanatos) itself so no one could die, then, dying, instructed his wife to skip the burial rites so he could return from Hades to scold her, and refused to go back. The punishment fits a man who out-clevered the cosmos twice.
Internet culture uses Sisyphus as shorthand for pointless grind, emails, fitness, laundry, missing that the original figure is a trickster, not a worker. His punishment is tailored irony: the man who would not accept limits receives one, forever.
Camus's whole reading hinges on one image: the descent, the moment Sisyphus walks back down the hill, conscious of his fate, and superior to it. 'One must imagine Sisyphus happy' (1942) works only because consciousness of pointlessness, chosen anyway, is revolt. The boulder is his, the essay concludes, the silent joy where his heart is.
If Sisyphus is happy, what is your excuse?
